Answer:
The sample of lithium occupies the largest volume.
Explanation:
Given the densities for the four elements, we have the expression that shows the relationship between mass and Volume to express the density of an element.
For each element we have:
The problem says that all the samples have the same mass, so:
it means that m is a constant
Now, solving for the Volume in each element and with m as a constant, we have:
If we assume m = 1g, we find that:
So we can see that the sample of lithium occupies the largest volume with 1.88mL
Note that m only can take positive values, so if you change the value of m, always will be the lithium which occupies the largest volume.
Answer:The molar mass of a compound cab be find by adding up all the molar mass of the element present in the compound... Check the image for more clarification

Answer:
Product: propan-1-ol
Explanation:
IIn this case, we have to remember that is a reduction agent. So, this is a <u>reduction reaction</u>. The has the ability to produce <u>hydride ions </u>. This ion can attack the <u>carbonyl group</u> generating a negative charge in the oxygen. In the next step, the negative charge in the oxygen can attack a water molecule to<u> protonate</u> the molecule and produce <u>propan-1-ol</u>.
See figure 1

Answer:
I would say A, Gravity can help erosion to occur.
Explanation:
While B,C,D do help cause erosion, that isn't the only way erosion can occur.
